Accurate code to restore minimized windows state

[Stilez 0]

I was playing round with WinMinimizeAll() and WinMinimizeAllUndo(). If you have popup dialogs etc in between, sometimes the WinMinimizeAllUndo() "forgets" which windows were minimized by WinMinimizeAll() so it doesn't do the restore function as you'd expect.

For anyone who hits this, the following code will handle it - and allow arbitrary window manipulation in between. It logs all non-minimized window handles, and when you're done, it checks for any windows that are displayed now, were displayed before (according to its handle) and whose state has changed from non-minimized to minimized, and restores it.

Things it doesn't do - it doesn't handle clashes of window handles, and it doesn't remember the active window (their Z-order). If anyone wants to fix for those, please do!

#Include <Array.au3>


dim $OriginalNonMinimizedWindows[1]
$OriginalNonMinimizedWindows[0]=""

$winlist  = WinList()
If $winlist[0][0] > 0 Then
    for $i = 1 to $winlist[0][0]
        $winhdl = $winlist[$i][1]
        $state = WinGetState($winhdl)
        If BitAND($state,16) <> 16 Then _ArrayAdd($OriginalNonMinimizedWindows, $winhdl)
    Next
EndIf
_ArraySort($OriginalNonMinimizedWindows)

WinMinimizeAll()
sleep (1500)

$winlist = Winlist()
If $winlist[0][0] > 0 Then
    For $i = 1 to $winlist[0][0]
        $winhdl = $winlist[$i][1]
        $state = WinGetState($winhdl)
        If BitAND($state, 16) == 16 Then
            If _ArrayBinarySearch($OriginalNonMinimizedWindows, $winhdl) >= 0 Then 
                WinSetState($winhdl, "", @SW_RESTORE)
                msgbox(1,"","Restored window for: " & $winlist[$i][0] & " (handle "& $winlist[$i][1] & ").", 1)
            EndIf
        EndIf
    Next
EndIf
